What is the "long tail effect"?

Long Tail Effect. "head" and "tail" are two statistical terms. The protruding part in the middle of the normal curve is called "head"; The relatively flat parts on both sides are called "tails".

from the perspective of people's needs, most of the needs will be concentrated in the head, and this part can be called popularity, while the demand distributed in the tail is personalized and scattered. This part of the differentiated and small demand will form a long "tail" on the demand curve, and the so-called long tail effect lies in its quantity. Adding up all the non-popular markets will form a market bigger than the popular market.

the origin of the long tail theory?

In October, 24, ChrisAnderson, editor-in-chief of Wired magazine in the United States, put forward the Long Tail theory for the first time in his article. He told readers that the future of business and culture lies not in the hot products, not in the head of the traditional demand curve, but in the infinite tail in the demand curve.
